Nowadays, one of the problems of human life is popula- tion congestion and the lack of ability to meet their needs. One of the important infrastructures affected by this issue is the transportation infrastructure. Moreover, increasing transportation facilities through conventional methods, due to the need for macro investment and much time, cannot be nowadays considered as a proper and practi- ...

abstract recognition of effective factors on landslide occurrence and so high and low hazard region is one of the most important and necessary works for mitigation of landslide damages. in this study, from all of the effective factors on landslide occurrence, land use changes and road construction, into a parts of tadjan watershed with area about 708.08 square kilometers in south of sari, was s...

This paper examines a new evaluation of urban road traffic safety based on a matter element analysis, avoiding the difficulties found in other traffic safety evaluations. The issue of urban road traffic safety has been investigated through the matter element analysis theory. The chief aim of the present work is to investigate the features of urban road traffic safety. Emphasis was placed on the...

Nowadays often a multiplicity of different spatial datasets exists for the same area. In order to use and maintain these datasets effectively they have to be integrated into a multiple representation database (MRDB). In an MRDB, the objects within the different datasets that model the same real-world phenomenon can be linked with each other. When integrating existing datasets these links have t...

To evaluate the layout adjustment scheme of bus line during subway construction, the method combining quantitative survey and fuzzy aggregation is used. One criterion is transit service level, which considered nonlinear coefficient, line length, transfer distance and average waiting time. Another criterion is traffic impact degree incorporating three factors: saturation degree on work-zone sect...
